Since I've been planning to build up a small convention store for the last few years, I went ahead and got started by making a discount card that can be passed out. It's based on a few others that I've seen, but I'm going to make this one valid until it's filled up completely, which means that if someone comes to a con, and leaves with it, they can meet me at another con and still continue filling it out. It will not be valid for online sales (there will be other discounts available) due to the impossibility of knowing whether it's the right card or not.
